Now the answer, that I am about to republish, is written to Tristan, aged 8. But frankly I have no doubt that the answer will be keenly read by persons of all ages. Certainly, this 75-year-old found the answer of great interest.
But to the question:
How can a Big Bang have been the start of the universe, since intense explosions destroy everything? – Tristan S., age 8, Newark, Delaware
And the answer:

How could an explosive Big Bang be the birth of our universe?
April 30, 2020
By Michael Lam, Assistant Professor of Physics and Astronomy, Rochester Institute of Technology
Pretend you’re a perfectly flat chess piece in a game of chess on a perfectly flat and humongous chessboard. One day you look around and ask: How did I get here? How did the chessboard get here? How did it all start? You pull out your telescope and begin to explore your universe, the chessboard….
What do you find? Your universe, the chessboard, is getting bigger. And over more time, even bigger! The board is expanding in all directions that you can see. There’s nothing that seems to be causing this expansion as far as you can tell – it just seems to be the nature of the chessboard.
But wait a minute. If it’s getting bigger, and has been getting bigger and bigger, then that means in the past, it must have been smaller and smaller and smaller. At some time, long, long ago, at the very beginning, it must have been so small that it was infinitely small.
Let’s work forward from what happened then. At the beginning of your universe, the chessboard was infinitely tiny and then expanded, growing bigger and bigger until the day that you decided to make some observations about the nature of your chess universe. All the stuff in the universe – the little particles that make up you and everything else – started very close together and then spread farther apart as time went on.
Our universe works exactly the same way. When astronomers like me make observations of distant galaxies, we see that they are all moving apart. It seems our universe started very small and has been expanding ever since. In fact, scientists now know that not only is the universe expanding, but the speed at which it’s expanding is increasing. This mysterious effect is caused by something physicists call dark energy, though we know very little else about it.

If astronomers look back all the way to the event that started our universe, we call that the Big Bang.
Many people hear the name “Big Bang” and think about a giant explosion of stuff, like a bomb going off. But the Big Bang wasn’t an explosion that destroyed things. It was the beginning of our universe, the start of both space and time. Rather than an explosion, it was a very rapid expansion, the event that started the universe growing bigger and bigger.
This expansion is different than an explosion, which can be caused by things like chemical reactions or large impacts. Explosions result in energy going from one place to another, and usually a lot of it. Instead, during the Big Bang, energy moved along with space as it expanded, moving around wildly but becoming more spread out over time since space was growing over time.
Back in the chessboard universe, the “Big Bang” would be like the beginning of everything. It’s the start of the board getting bigger.
It’s important to realize that “before” the Big Bang, there was no space and there was no time. Coming back to the chessboard analogy, you can count the amount of time on the game clock after the start but there is no game time before the start – the clock wasn’t running. And, before the game had started, the chessboard universe hadn’t existed and there was no chessboard space either. You have to be careful when you say “before” in this context because time didn’t even exist until the Big Bang.
You also have wrap your mind around the idea that the universe isn’t expanding “into” anything, since as far as we know the Big Bang was the start of both space and time. Confusing, I know!
Astronomers aren’t sure what caused the Big Bang. We just look at observations and see that’s how the universe did start. We know it was extremely small and got bigger, and we know that kicked off 13.8 billion years ago.
What started our own game of chess? That’s one of the deepest questions anyone can ask.
ooOOoo
Before the Big Bang then there was “no space and there was no time.” Michael Lam says that is confusing. I think that’s a gigantic understatement.
There there’s Dark Energy!
I wonder if we humans will ever come to the point where it is all understood!
There was such a good response to the article on the Hubble that I published on April 27th that it was an easy decision to republish the article that was presented on the BBC website on the 24th, and this time the photographs can be downloaded.
By Jonathan Amos, Science correspondent, 24 April 2020
It’s 30 years ago to the day that the Hubble telescope was launched – and to celebrate its birthday, the veteran observatory has produced another astonishing image of the cosmos.
This one is of a star-forming region close to our Milky Way Galaxy, about 163,000 light-years from Earth.
The larger object is the nebula NGC 2014; its companion is called NGC 2020.
But astronomers have nicknamed the scene the “Cosmic Reef” because it resembles an undersea world.
[There is an audio by Antonella Nota that is a little under 10 minutes long. I cannot embed it into this post for some unclear reason. Go here if you want to listen to it! It’s well worth listening to.]
Antonella Nota: “It’s called the people’s telescope because it brought the Universe to the people”
Famously blighted by blurred vision at the outset of its mission in 1990, Hubble was eventually repaired and upgraded.
The remarkable pictures it has taken of planets, stars, and galaxies have transformed our view of the cosmos.
Indeed, there are those who think Hubble is the most important scientific tool ever built.
It’s still far from retirement.
The US space agency (Nasa), which runs the observatory in partnership with the European Space Agency (Esa), says operations will be funded for as long as they remain productive.
Last year, its data resulted in almost 1,000 scientific papers being published – so it continues to stand at the forefront of discovery.
For its 25th birthday, Hubble imaged a giant cluster of stars called Westerlund 2
Engineers obviously keep a watching brief on the health of Hubble’s various systems. Pleasingly, all four instruments onboard – the two imagers and two spectrographs – work at full tilt.
In the past, the telescope’s Achilles heel has been the six gyroscopes that help turn and point the facility, maintaining a rock-steady gaze at targets on the sky.
These devices have periodically failed down the years, and during their final servicing mission in 2009 space shuttle astronauts were tasked with replacing all six.
Three have subsequently shut down again, but Nasa project scientist Dr Jennifer Wiseman says this is not yet an issue for serious concern.
“Nominally, we need three gyroscopes, but we can operate on just one due to the ingenuity of the engineers,” she asserted.
There’s a quiet confidence that Hubble can keep working well into the 2020s. Its supposed “successor” – the James Webb Space Telescope (JWST) – is due for launch next year, but the presence in orbit of this more modern observatory will in truth merely just extend capability; it won’t make Hubble redundant.
That’s because the new facility has been designed to see the cosmos at longer wavelengths of light than Hubble. The duo will be complementary and will on occasion actually pursue targets together to get a fuller perspective.
This is an exciting prospect for astronomers everywhere – but especially for those in Europe where Hubble has been such a rewarding endeavour, says Esa project scientist Dr Antonella Nota.
“From the memorandum of understanding there was a guarantee that European astronomers would get 15% of observing time for the duration of the mission. If I look back at how much time European astronomers got – on average it’s 22%. And it is a peer-reviewed process so we never needed to put a finger on the scales. European astronomers are creative; they’re smart; they’re doing leading-edge science,” she told BBC News.
What has Hubble contributed to science?
It’s a bit of a cliche, but Hubble has truly been a “discovery machine”.
Before the telescope launched in 1990, astronomers didn’t know whether the Universe was 10 billion years old or 20 billion years old.
Hubble’s survey of pulsating stars narrowed the uncertainty, and we now know the age extremely well, at 13.8 billion.
The observatory played a central role in revealing the accelerating expansion of the cosmos – a Nobel Prize-winning breakthrough – and it provided the definitive evidence for the existence of super-massive black holes at the centre of galaxies.
The Deep Field images require Hubble to stare at the same patch of sky for days on end
It’s amazing to think that when Hubble launched, scientists had yet to detect the first exoplanet, the name given to a planet orbiting a star other than our Sun. Today, Hubble is pioneering the study of these far-off worlds, examining their atmospheres to try to gauge their nature.
And although the sparkling eight-metre-class ground-based telescopes can now match – and even exceed – Hubble’s skill in certain fields of study, the space telescope remains peerless in going super-deep.
Its so-called Deep Field observations in which it stared at a small patch of sky for days on end to identify the existence of very distant, extremely faint galaxies is one of the towering achievements in astronomy.
These studies have shown us what the Universe was like just a few hundred million years after the Big Bang. Only JWST, with its finely-tuned infrared detectors, will go deeper still.
A Hubble classic: The Veil Nebula is the expanding debris of an exploded star
Kathryn Sullivan was one of the astronauts onboard Space Shuttle Discovery when it released Hubble into its 612km-high orbit on 25 April, 1990 – a day she recounts in a recent book, Handprints On Hubble.
“Hubble’s scientific impact has just been immense. But what I had not really appreciated until I started writing my book was the extent to which Hubble – because of its gorgeous images and their mind-bending implications – has really permeated popular culture,” she told BBC News.
“I see Hubble on the side of U-Haul (rental) trailers, on tattoos, on lunchboxes, on shirts, in advertisements, almost ubiquitously.
“And I think part of that is down to Hubble coming into service just as the internet was becoming the thing we now know it to be.
“That’s put the pictures right in front of people.”
JWST will study the Universe at longer wavelengths of light
ooOOoo
This is the most amazing invention and regular missions to service the telescope including regular updates to the technology have kept it current.
It has produced the most distant and beautiful photographs. It has also refined our knowledge of when the universe came into existence – 13.8 billion years ago.
Then in a very short time it will be May 8th. Not only my half-birthday but considerably of more note the anniversary of the end of World War II.
I am certain that I am the only one who puts meaning into these dates. I can do no better than to re-post something that I published on May 1st, 2017.
ooOOoo
For all my life this has felt like a very special month.
And, dear friends, at the risk of repeating myself to many of you, this is why the month of May is special for me.
Simply that I was born in London during the closing months of the Second World War. Inevitably, I was unaware of the number of German bombs that were falling on London during those last few months. But there were thousands.
On May 8th. 1945, the day that WWII ended and six months to the day from when I was born, my mother looked down at me and said aloud to me: “You are going to live”. Despite the fact that I don’t recall my mother saying that, it was verified many times later when I was growing up.
Now here we are approaching May 8th. 2017 (now May, 2020) and in a very real sense it seems that we are in another war.
A war of consequence.
A war that we have been engaged in for many, many years.
A war where we are inadvertently fighting on a global battlefield.
A war where 99.99% of us don’t consciously identify the weapons we are using. Weapons that are incredibly effective. So much so that we are in sight of winning the last battle; winning the war.
Yet a war where winning is no win at all. Indeed, where winning this war, this global war, spells the end. The end of life for 99.99% of us humans (and much else besides).
Now what on earth has got me so fired up?
Two things have:
The first is that I am living in my 73rd year of life. (Now 75th.) I have no idea of when my life comes to an end. But that death is a guarantee. Indeed, if one takes note of the average life expectancy of a male today in the USA (75.6 years) , it may not be that far away.
The second thing is that before my death I truly want to know that humankind has laid down its weapons of war against our planet and that there really is an unstoppable mission, a united wave of passion, to live in peace on this planet. Perhaps better put to live in peace with this planet.
Or in the words of an organization that I now want to introduce:
A mission which will require the hard work and dedication of each and every one of us as we do everything in our power as individuals, but also as we galvanize businesses, entrepreneurs, innovators, city planners, communities, people and politicians—all those who share our purpose.
OK! Thank you if you are still reading this! (Someone give Fred in that soft arm-chair over there a nudge; I can hear his snores from here!)
In the last Smithsonian electronic newsletter that I was reading yesterday morning there was a reference to an organization that I hadn’t previously come across. Here is the link to that item on The Smithsonian website. I am republishing it in full in this place. As you read it you will understand why I am republishing it.

Using a New Roadmap to Democratize Climate Change
A new tool aims to bypass governments and put the power of climate action in the people’s hands
Olafur Grimsson, who was president of Iceland from 1996 to 2016 and saw his country through the worst economic crisis in its history, making headlines all over the world as banks collapsed and the country fell into a depression, is the very picture of an urbane statesman. Collected and poised, with a striking full head of white hair, as comfortable in English as in his native Icelandic, he seems an unlikely revolutionary, not the sort of person you’d look at and immediately find yourself thinking: “Power to the People.”
But Grimsson is one of the primary architects of a quietly radical new idea whose aim is to facilitate action on climate change without any of the usual suspects—governments, countries, international bodies, negotiating parties.
He and several other veterans of the historic 2015 Paris Agreement on climate change were in Washington, D.C., last year, just before COP22, the climate meeting held in Marrakesh in 2016. They were pondering next steps when the conversation took a new and interesting turn, Grimsson says, addressing the question: “Was it possible to have the success of Paris without governments necessarily being in the leading role?”
The group included movers and shakers such as Peter Seligmann, the chairman of Conservation International; Laurene Powell Jobs, president of the philanthropic organization the Emerson Collective; and Andy Karsner, an assistant energy secretary during the administration of George W. Bush. Galvanized by their own query, they decided to try to answer it—to set about creating a new tool to aid in achieving the goals of the Paris accord.
At the Smithsonian’s Earth Optimism Summit, a gathering this past weekend of conservation-minded citizens, scientists and activists, Grimsson explained: “You get governments that are opposed or even hostile to climate action. We decided to bring together in Marrakesh a gathering of thinkers and scientists and innovators and policymakers from different countries in order to discuss a new model of securing the success of the future of the climate movement.”
At the Smithsonian’s Earth Optimism Summit, the former president of Iceland Olafur Grimsson encouraged new solutions to climate change, awarding cash prizes to the winners of the “Make for the Planet” challenge. (The Roadmap)
Grimsson’s group felt that due to changes in information technology and social transformations, the large organizations and structures that used to be necessary to effect change were now not needed. And thus was born Roadmap, a new crowdsourcing tool for anyone and everyone interested in climate action. Still in its very early stages, Roadmap’s founders envision it as a platform for those working on climate issues—from scientist and policymaker to farmer and fisherman—to facilitate the sharing of knowledge and ideas, methods and techniques.
“A new political model is possible—where everyone can be a doer, where you no longer need big government or big enterprises to bring about success,” Grimsson says.
This new model for social change that skips the usual cumbersome channels and processes has been seen everywhere from public health, where the Bill & Melinda Gates Foundation has redefined the sector, to the hospitality industry, which is working to combat the human trafficking that plagues its businesses, to perhaps most famously the Arab Spring, where the role of social media in bringing about political change is still being debated today.
And this new model is complemented by technological changes. “The innovation in energy technology is such that we no longer have to wait for the big energy breakthrough,” Grimsson says. “We already have the available technologies. Every individual, home, village, community, town and region can execute change. The good news from the climate point of view is that, in addition to the information technology revolution, there has now also taken place an energy revolution. A house can be a power station: If the people who live in that house have extra energy, they can sell their energy through the smart grid. The notion that every house can be a power station is as revolutionary as saying that every mobile phone can be a media company.”
Grimsson admits that it may seem odd for someone in his position to be advocating that ordinary citizens take action apart from the conventional corridors of governmental power.
“For me to say that these traditional political organizations and positions are somewhat outdated is perhaps a strange statement: I was a professor of political science, I’ve been a member of parliament, I’ve been a minister of finance, I was president for 20 years,” he says.
It was during Iceland’s financial meltdown that he first experienced this new kind of social change: “I saw this very strongly through the financial crisis in my own country, which led to a big social economic uprising. All those activities were engineered by unknown people, people who were not part of a big organization, who used Facebook and the information media to bring thousands of people together in one day.”
Right now, Roadmap consists of a website and a lofty manifesto that speaks of raising the value of “moral currency” and creating a “best practices warehouse.” Visitors to the site can fill out a form if they want to become part of its community of “doers.” The practical part of the manifesto speaks of identifying the best methodologies and models; implementing a “real-time system of measurement” and a way to “gauge and understand what is working, what is not, and exactly what is being achieved.” As the platform develops, it will be interesting to see exactly what form these gauges, measurement systems, and warehouses take.
After the Paris Agreement, Grimsson says of himself and his Roadmap co-founders, “We were all optimistic, but we are all also realists.” It is his belief that if you “give people the tools, they can execute the transformation and the change—without governmental leadership.” Perhaps Roadmap will be one of those tools.

Here’s a video that spells it out in ways that I find impossible to ignore.
Because in hundreds of years time I want others to look at the following picture of Troutbeck Valley in England and know how precious is this one and only planet we live on.
We are witnessing more storms, more unseasonal weather patterns, and I just hope that we wake up soon to the damage we are doing to our beloved Mother that has held us in her eternal arms for so long..

Enjoy the month of May wherever you are in the world!
Closing by repeating a key pronouncement in that RoadMap video above:
My how the years go by!
Back in 2010 I wrote about the Hubble, wishing it Happy Birthday!
Now here we are in 2020 and, again, I want to feature this most amazing space telescope ever.
The thirtieth anniversary of the launch of the Hubble Space Telescope was on the 24th April, 2020, just three days ago.
The challenge is that the photographs that go with the article are not permitted to be shared with you. So I have grabbed some others that, apparently, are alright.

How the Hubble Space Telescope opened our eyes to the first galaxies of the universe
April 24, 2020
By Professor Rodger Thompson, Professor of Astronomy, University of Arizona
The Hubble Space Telescope launched on the 24th of April, 30 years ago. It’s an impressive milestone especially as its expected lifespan was just 10 years.
One of the primary reasons for the Hubble telescope’s longevity is that it can be serviced and improved with new observational instruments through Space Shuttle visits.
When Hubble, or HST, first launched, its instruments could observe ultraviolet light with wavelengths shorter than the eye can see, as well as optical light with wavelengths visible to humans. A maintenance mission in 1997 added an instrument to observe near infrared light, which are longer wavelengths than people can see. Hubble’s new infrared eyes provided two new major capabilities: the ability to see farther into space than before and see deeper into the dusty regions of star formation.
I am an astrophysicist at the University of Arizona who has used near infrared observations to better understand how the universe works, from star formation to cosmology. Some 35 years ago, I was given the chance to build a near infrared camera and spectrometer for Hubble. It was the chance of a lifetime. The camera my team designed and developed has changed the way humans see and understand the universe. The instrument was built at Ball Aerospace in Boulder, Colorado, under our direction.
Seeing further and earlier
Edwin Hubble, HST’s namesake, discovered in the early 1900s that the universe is expanding and that the light from distant galaxies was shifted to longer, redder wavelengths, a phenomenon called the redshift. The greater the distance, the larger the shift. This is because the further away an object is, the longer it takes for the light to reach us here on Earth and the more the universe has expanded in that time.
The Hubble ultraviolet and optical instruments had taken images of the most distant galaxies ever seen, known as the Northern Hubble Deep Field, or NHDF, which were released in 1996. These images, however, had reached their distance limit due to the redshift, which had shifted all of the light of the most distant galaxies out of the visible and into the infrared.
One of the new instruments added to Hubble in the second maintenance mission has the awkward name, the Near Infrared Camera and Multi-Object Spectrometer, NICMOS, pronounced “Nick Moss.” The near infrared cameras on NICMOS observed regions of the NHDF and discovered even more distant galaxies with all of their light in the near infrared.
Astronomers have the privilege of watching things happen in the past which they call the “lookback time.” Our best measurement of the age of the universe is 13.7 billion years. The distance that light travels in one year is called a light year. The most distant galaxies observed by NICMOS were at a distance of almost 13 billion light years. This meant that the light that NICMOS detected had been traveling for 13 billion years and showed what the galaxies looked like 13 billion years ago, a time when the universe was only about 5% of its current age. These were some of the first galaxies ever created and were forming new stars at rates that were more than a thousand times the rate at which most galaxies form stars in the current universe.
Hidden by dust
Although astronomers have studied star formation for decades, many questions remain. Part of the problem is that most stars are formed in clouds of molecules and dust. The dust absorbs the ultraviolet and most of the optical light emitted by forming stars, making it difficult for Hubble’s ultraviolet and optical instruments to study the process.
The longer, or redder, the wavelength of the light, the less is absorbed. That is why sunsets, where the light must pass through long lengths of dusty air, appear red.
The near infrared, however, has an even easier time passing through dust than the red optical light. NICMOS can look into star formation regions with the superior image quality of Hubble to determine the details of where the star formation occurs. A good example is the iconic Hubble image of the Eagle Nebula, also known as the pillars of creation.
The optical image shows majestic pillars which appear to show star formation over a large volume of space. The NICMOS image, however, shows a different picture. In the NICMOS image, most of the pillars are transparent with no star formation. Stars are only being formed at the tip of the pillars. The optical pillars are just empty dust reflecting the light of a group of nearby stars.
The dawning of the age of infrared
When NICMOS was added into the HST in 1997 NASA had no plans for a future infrared space mission. That rapidly changed as the results from NICMOS became apparent. Based on the data from NICMOS, scientists learned that fully formed galaxies existed in the universe much earlier than expected. The NICMOS images also confirmed that the expansion of the universe is accelerating rather than slowing down as previously thought. The NHDF infrared images were followed by the Hubble Ultra Deep Field images in 2005, which further showed the power of near infrared imaging of distant young galaxies. So NASA decided to invest in the James Webb Space Telescope, or JWST, a telescope much larger than HST and completely dedicated to infrared observations.
On Hubble, a near infrared imager was added to the third version of the Wide Field camera which was installed in May of 2009. This camera used an improved version of the NICMOS detector arrays that had more sensitivity and a wider field of view. The James Webb Space Telescope has much larger versions of the NICMOS detector arrays that have more wavelength coverage than the previous versions.
The James Webb Space Telescope, scheduled to be launched in March 2021, followed by the Wide Field Infrared Survey Telescope, form the bulk of future space missions for NASA. These programs were all spawned by the near infrared observations by HST. They were enabled by the original investment for a near infrared camera and spectrometer to give Hubble its infrared eyes. With the James Webb Space Telescope, astronomers expect to see the very first galaxies that formed in the universe.

The spiral galaxy NGC 2008 sits centre stage, its ghostly spiral arms spreading out towards us, in this image captured by the NASA/ESA Hubble Space Telescope. This galaxy is located about 425 million light-years from Earth in the constellation of Pictor (The Painter’s Easel). Discovered in 1834 by astronomer John Herschel, NGC 2008 is categorised as a type Sc galaxy in the Hubble sequence, a system used to describe and classify the various morphologies of galaxies. The “S” indicates that NGC 2008 is a spiral, while the “c” means it has a relatively small central bulge and more open spiral arms. Spiral galaxies with larger central bulges tend to have more tightly wrapped arms, and are classified as Sa galaxies, while those in between are classified as type Sb. Spiral galaxies are ubiquitous across the cosmos, comprising over 70% of all observed galaxies — including our own, the Milky Way. However, their ubiquity does not detract from their beauty. These grand, spiralling collections of billions of stars are among the most wondrous sights that have been captured by telescopes such as Hubble, and are firmly embedded in astronomical iconography.
oooo
The NASA/ESA Hubble Space Telescope has revisited one of its most iconic and popular images: the Eagle Nebula’s Pillars of Creation. This image shows the pillars as seen in infrared light, allowing it to pierce through obscuring dust and gas and unveil a more unfamiliar — but just as amazing — view of the pillars. In this ethereal view the entire frame is peppered with bright stars and baby stars are revealed being formed within the pillars themselves. The ghostly outlines of the pillars seem much more delicate, and are silhouetted against an eerie blue haze. Hubble also captured the pillars in visible light.
Rodger I. Thompson was the Principal Investigator for the Near Infrared Camera and Multi-Object Spectrometer, NICMOS. He was responsible for the execution of a contract to Arizona Board of Regents from NASA to deliver NICMOS as a Hubble Space Telescope Instrument and carry out a scientific investigation with it. Prof. Thompson received summer salary from this contract at his University pay rate during the execution of the contract which ended in 2004. Prof. Thompson is not currently receiving any external funding.

Now for two YouTube videos.
The first is a celebration of the 30th anniversary.
And the second is slightly longer but conveys images taken from the telescope. I have no doubt that you will love them as we did!
Both these videos are beyond words! That we are alive today and can share these videos on this blog is stupendous!
I wanted to let the post on Tuesday run for a couple of days because it really made the point about dogs, in particular, being animals who love to love!
But I then forgot, until I woke up on the 22nd, that yesterday was Earth Day.
So what to publish?
Yesterday in Merlin was a damp day with a steady rain coming down in the morning. About 10am I volunteered the idea that we should drive the shortish distance to Galice; just 10 miles from where we live. Galice is a very small settlement on the Western bank of the Rogue River. Then we drove on for a few more miles. It was incredible scenery. The misty, damp forest and the river running below in the gorge.
I had my camera with me and the following are some of the photographs that were taken.
Just for a change! All within 15 miles of home!

For those interested in learning more, I am publishing the WikiPedia account of the Rogue River.
The Rogue River (Tolowa: yan-shuu-chit’ taa-ghii~-li~’,[7]Takelma: tak-elam[8]) in southwestern Oregon in the United States flows about 215 miles (346 km) in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewaterrafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968. Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains. In the Kalmiopsis Wilderness section of the Rogue basin are some of the world’s best examples of rocks that form the Earth’s mantle. Near the mouth of the river, the only dinosaur fragments ever discovered in Oregon were found in the Otter Point Formation, along the coast of Curry County.
People have lived along the Rogue River and its tributaries for at least 8,500 years. European explorers made first contact with Native Americans (Indians) toward the end of the 18th century and began beaver trapping and other activities in the region. Clashes, sometimes deadly, occurred between the natives and the trappers and later between the natives and European-American miners and settlers. These struggles culminated with the Rogue River Wars of 1855–56 and removal of most of the natives to reservations outside the basin. After the war, settlers expanded into remote areas of the watershed and established small farms along the river between Grave Creek and the mouth of the Illinois River. They were relatively isolated from the outside world until 1895, when the Post Office Department added mail-boat service along the lower Rogue. As of 2010, the Rogue has one of the two remaining rural mail-boat routes in the United States.
Dam building and removal along the Rogue has generated controversy for more than a century; an early fish-blocking dam (Ament) was dynamited by vigilantes, mostly disgruntled salmon fishermen. By 2009, all but one of the main-stem dams downstream of a huge flood-control structure 157 miles (253 km) from the river mouth had been removed. Aside from dams, threats to salmon include high water temperatures. Although sometimes too warm for salmonids, the main stem Rogue is relatively clean, ranking between 85 and 97 (on a scale of 0 to 100) on the Oregon Water Quality Index (OWQI).
Although the Rogue Valley near Medford is partly urban, the average population density of the Rogue watershed is only about 32 people per square mile (12 per km2). Several historic bridges cross the river near the more populated areas. Many public parks, hiking trails, and campgrounds are near the river, which flows largely through forests, including national forests. Biodiversity in many parts of the basin is high; the Klamath-Siskiyou temperate coniferous forests, which extend into the southwestern Rogue basin, are among the four most diverse of this kind in the world.

Just to reflect on the fact that people have lived along the Rogue River and its tributaries for 8,500 years!
We were truly alone when we went to Utah. (September, 2019.)
But then again, one of the privileges of being on 13 acres, 13 very rural acres, here in Southern Oregon is that being alone is not that far away!
I don’t want to underplay the importance of this posting, republished from The Conversation website (with permission), because we live in so busy times.

Spending time alone in nature is good for your mental and emotional health
June 4th, 2018
By Brad Daniel, Professor of Outdoor Education, Montreat College Andrew Bobilya, Associate Professor and Program Director of Parks and Recreation Management, Western Carolina University
Ken Kalisch, Associate Professor of Outdoor Education, Montreat College Today Americans live in a world that thrives on being busy, productive and overscheduled. Further, they have developed the technological means to be constantly connected to others and to vast options for information and entertainment through social media. For many, smartphones demand their attention day and night with constant notifications.
As a result, naturally occurring periods of solitude and silence that were once commonplace have been squeezed out of their lives. Music, reality TV shows, YouTube, video games, tweeting and texting are displacing quiet and solitary spaces. Silence and solitude are increasingly viewed as “dead” or “unproductive” time, and being alone makes many Americans uncomfortable and anxious.
We study and teach outdoor education and related fields at several colleges and organizations in North Carolina, through and with other scholars at 2nd Nature TREC, LLC, a training, research, education and consulting firm. We became interested in the broader implications of alone time after studying intentionally designed solitude experiences during wilderness programs, such as those run by Outward Bound. Our findings reveal that time alone in nature is beneficial for many participants in a variety of ways, and is something they wish they had more of in their daily life.

Reflection and challenge
We have conducted research for almost two decades on Outward Bound and undergraduate wilderness programs at Montreat College in North Carolina and Wheaton College in Illinois. For each program, we studied participants’ experiences using multiple methods, including written surveys, focus group interviews, one-on-one interviews and field notes. In some cases, we asked subjects years later to look back and reflect on how the programs had affected them. Among other questions, our research looked at participant perceptions of the value of solo time outdoors.
Our studies showed that people who took part in these programs benefited both from the outdoor settings and from the experience of being alone. These findings build on previous research that has clearly demonstrated the value of spending time in nature.
Scholars in fields including wilderness therapy and environmental psychology have shown that time outdoors benefits our lives in many ways. It has a therapeutic effect, relieves stress and restores attention. Alone time in nature can have a calming effect on the mind because it occurs in beautiful, natural and inspirational settings.

Nature also provides challenges that spur individuals to creative problem-solving and increased self-confidence. For example, some find that being alone in the outdoors, particularly at night, is a challenging situation. Mental, physical and emotional challenges in moderation encourage personal growth that is manifested in an increased comfort with one’s self in the absence of others.
Being alone also can have great value. It can allow issues to surface that people spend energy holding at bay, and offer an opportunity to clarify thoughts, hopes, dreams and desires. It provides time and space for people to step back, evaluate their lives and learn from their experiences. Spending time this way prepares them to re-engage with their community relationships and full work schedules.
Putting it together: The outdoor solo
Participants in programmed wilderness expeditions often experience a component known as “Solo,” a time of intentional solitude lasting approximately 24-72 hours. Extensive research has been conducted on solitude in the outdoors because many wilderness education programs have embraced the educational value of solitude and silence.
Solo often emerges as one of the most significant parts of wilderness programs, for a variety of reasons. Alone time creates a contrasting experience to normal living that enriches people mentally, physically and emotionally. As they examine themselves in relation to nature, others, and in some cases, God, people become more attuned to the important matters in their lives and in the world of which they are part.
Solo, an integral part of Outward Bound wilderness trips, can last from a few hours to 72 hours. The experience is designed to give participants an opportunity to reflect on their own thoughts and critically analyze their actions and decisions.
Solitary reflection enhances recognition and appreciation of key personal relationships, encourages reorganization of life priorities, and increases appreciation for alone time, silence, and reflection. People learn lessons they want to transfer to their daily living, because they have had the opportunity to clarify, evaluate and redirect themselves by setting goals for the future.
For some participants, time alone outdoors provides opportunity to consider the spiritual and/or religious dimension of life. Reflective time, especially in nature, often enhances spiritual awareness and makes people feel closer to God. Further, it encourages their increased faith and trust in God. This often occurs through providing ample opportunities for prayer, meditation, fasting, Scripture-reading, journaling and reflection time.
Retreating to lead
As Thomas Carlyle has written, “In (solitary) silence, great things fashion themselves together.” Whether these escapes are called alone time, solitude or Solo, it seems clear that humans experience many benefits when they retreat from the “rat race” to a place apart and gather their thoughts in quietness.
In order to live and lead effectively, it is important to be intentional about taking the time for solitary reflection. Otherwise, gaps in schedules will always fill up, and even people with the best intentions may never fully realize the life-giving value of being alone.
ooOOoo
I would modify that advice from Thomas Carlyle and that is to include a dog.
For in my experience when one is in the mood for a bit of solitary reflection your dog seems to sense it as well.
I opened my email box a couple of days ago and there was an email from Sarah.
It said:
Hi there!
I would be honored to be a guest writer for your blog and of course would reciprocate. I hope you don’t mind that I shared your link in my last post. I am not totally sure if blogging etiquette.

Of course I said yes!
Sarah’s background is sociology and she has a degree in the subject. Just as important she owns a dog walking business. I will let her finish her background:
I believe in living life to the fullest.
My daughter is a Cancer survivor- and as a result of that journey- It put my life into perspective. I learned to never take anything for granted- you never know what’s around the next corner. I am continuing to work on becoming the best version of me, while making the most of each and everyday.
Frankly, I do not really know what it is like to have a daughter, or a son come to it, go down with cancer. The nearest I have come to the disease was when I had just turned 12 and my father died of lung cancer.
So here’s her guest post.

Start your day with music- not the News! Surviving the Coronavirus with mindfulness Day 2
By Sarah Kinneavy, March 28th, 2020
As I continue to try to stay calm with mass panic happening across the globe 🌎 with this pandemic. As I mentioned in yesterday’s post:
Yesterday one of my friends posted on Facebook to start the day off with music – rather than the news! What a great idea!!! So, yesterday, as I got ready for a job interview and I waited until it was late enough in Hawaii to do my daily well check on my daughter there (she is in isolation in a dorm room – I am not sure if she has the dreaded virus or not). I used music as the focal point of this mindfulness exercise. This 15 minutes of focusing on the music- listening to the rhythm helped keep me present. I wasn’t worrying about getting the job or how my daughter was doing. I was just in that moment of getting ready with the accompaniment of music. It was honestly 15 minutes of pure happiness. What a great way to start my day! One thing I have to add – I try to not let myself think about what the words of the songs mean to me, or when I first heard the song. I just listen and enjoy. Okay- I may have danced around my apartment a bit too!
I can tell you – I did not feel anxious going to my interview like I normally would. I didn’t panic about my daughter’s health – I was able to wait until after my interview to check in on her. Mindfulness does not keep me from ever worrying about my kiddo or the world around me. No – I still worry – but It isn’t swallowing me up whole. And this is key!
Heading to my job interview.
I can’t wait to talk to you again tomorrow . How are you coping with all the stress and anxiety?
ooOOoo
That’s a lovely guest post!
And the message is clear and powerful: “No – I still worry – but It isn’t swallowing me up whole. And this is key!“
My grandson, Morten, who had his birthday yesterday, he is now nine, took some photographs recently. They are fabulous and are republished here with Morten’s permission. Completely untouched by yours truly!

Curiosity rover on Mars snags highest-resolution panorama yet
Posted by Eleanor Imster in Space | Today’s Image|March 5, 2020
This just in … a new super-cool composite from Curiosity on Mars. The panorama contains more than 1,000 images taken last Thanksgiving and assembled over the past few months … 1.8 billion new pixels of Martian landscape!
Yesterday (March 4, 2020) NASA released a panoramic image of the Martian surface captured by the Curiosity rover. It’s the highest-resolution panorama yet of the planet’s surface.
Composed of more than 1,000 images taken during the 2019 Thanksgiving holiday and carefully assembled over the ensuing months, the composite contains 1.8 billion pixels of Martian landscape. The rover’s Mast Camera, or Mastcam, used its telephoto lens to produce the panorama; meanwhile, it relied on its medium-angle lens to produce a lower-resolution, nearly 650-million-pixel panorama that includes the rover’s deck and robotic arm.
The panorama showcases Glen Torridon, a region on the side of Mount Sharp that Curiosity is exploring. They were taken between November 24 and December 1, 2019, when the mission team was out for the Thanksgiving holiday. NASA said:
Sitting still with few tasks to do while awaiting the team to return and provide its next commands, the rover had a rare chance to image its surroundings from the same vantage point several days in a row.

It required more than 6 1/2 hours over the four days for Curiosity to capture the individual shots. Mastcam operators programmed the complex task list, which included pointing the rover’s mast and making sure the images were in focus. To ensure consistent lighting, they confined imaging to between noon and 2 p.m. local Mars time each day.
In 2013, Curiosity produced a 1.3-billion-pixel panorama using both Mastcam cameras; its black-and-white Navigation Cameras, or Navcams, provided images of the rover itself.
Bottom line: Highest-resolution yet panorama of Martian surface by Mars Curiosity rover.

When one stops and reflects one can’t hide the scale of progress that humans have achieved. It is incredible!
It is also a struggle to take the situation so expertly spoken about by George Monbiot in yesterday’s post and square it with the achievement covered in today’s post.
Today and tomorrow I am posting essays that have nothing to do with dogs! Today, I am sharing George’s gloom about the future, tomorrow I am sharing our human capacity for incredible ingenuity and technology.
Because I sense we are a species of two extremes; the very mad and the very clever!
I don’t have an answer but I can share these two essays.
Our legal action against the government aims to shut down fossil fuels
By George Monbiot, published in the Guardian 4th March 2020
Our survival is not an afterthought. The defence of the living planet cannot be tacked retrospectively onto business as usual. Yet this is how almost all governments operate. They slap the word “sustainable” on damaging projects they have already approved, then insist this means they’ve gone green. If we are to survive and prosper, everything must change. Every decision should begin with the question of what the planet can withstand.
This means that any discussion about new infrastructure should begin with ecological constraints. The figures are stark. A paper published in Nature last year showed that existing energy infrastructure, if it is allowed to run to the end of its natural life, will produce around 660 gigatonnes of CO2. Yet, to stand a reasonable chance of preventing more than 1.5°C of global heating, we can afford to release, in total, no more than 580 gigatonnes. In other words, far from building new fossil power plants, the survival of a habitable planet means retiring the damaging projects that have already been built. Electricity plants burning coal and gas and oil will not secure our prosperity. They will destroy it.
But everywhere special interests dominate. Construction projects are driven, above all, by the lobbying of the construction industry, consultancies and financiers. Gigantic and destructive schemes, such as the Oxford-Cambridge Expressway, are invented by lobbyists for the purpose of generating contracts. Political support is drummed up, the project achieves its own momentum, then, belatedly, a feeble attempt is made to demonstrate that it can somehow become compatible with environmental promises. This is what destroys civilisations: a mismatch between the greed of economic elites and the needs of society.
But last week, something momentous happened. The decision to build a scheme with vast financial backing and terrible environmental impacts was struck down by the Court of Appeal. The judges decided that government policy, on which planning permission for a third runway at Heathrow was based, had failed to take account of the UK’s climate commitments, and was therefore unlawful. This is – or should be – the end of business as usual.
On Tuesday, we delivered a “letter before action” to the Treasury solicitor. We’ve given the government 21 days to accept our case and change its policy to reflect the climate commitments agreed by Parliament. If it fails to do so, we shall issue proceedings in the High Court to have the policy declared unlawful. We’ll need money, so we’ve launched a crowdfunding appeal to finance the action.
It’s hard to see how the government could resist our case. The Heathrow judgement hung on the government’s national policy statement on airports. This, the judges found, had not been updated to take account of the Paris climate agreement. New fossil fuel plants, such as the gas burners at Drax in Yorkshire the government approved last October, are enabled by something very similar: the national policy statements on energy infrastructure. These have not been updated since they were published in 2011. As a result, they take no account of the Paris agreement, of the government’s new climate target (net zero by 2050, as opposed to an 80% cut) or of Parliament’s declaration of a climate emergency. The main policy statement says that the European Emissions Trading System “forms the cornerstone of UK action to reduce greenhouse gas emissions from the power sector”. As we have left the EU, this, obviously, no longer holds. The planning act obliges the government to review its national policy statements when circumstances change. It has failed to do so. It is disregarding its own laws.
These outdated policy statements create a presumption in favour of new fossil fuel plants. Once a national policy statement has been published, there is little objectors can do to prevent damaging projects from going ahead. In approving the Drax plant, the secretary of state for business and energy at the time (Andrea Leadsom) insisted that the policy statement came first, regardless of the climate impacts. Catastrophic decisions like this will continue to be made until the statements change. They are incompatible with either the government’s new climate commitments or a habitable planet.
While we are challenging the government’s energy policies, another group – the Transport Action Network – is about to challenge its road building schemes on the same basis. It points out that the national policy statement on road networks is also outdated and incompatible with the UK’s climate commitments. The policy statement, astonishingly, insists that “any increase in carbon emissions is not a reason to refuse development consent“, unless the increase is so great that the road would prevent the government from meeting its national targets. No single road project can be disqualified on these grounds. But the cumulative effect of new road building ensures that the UK will inevitably bust its carbon targets. While carbon emissions are officially disregarded, minuscule time savings are used to justify massive and damaging projects.
Transport emissions have been rising for the past five years, partly because of road building. The government tries to justify its schemes by claiming that cars will use less fossil fuel. But because they are becoming bigger and heavier, new cars sold in the UK now produce more carbon dioxide per kilometre than older models.
The perverse and outdated national policy statement locks into place such damaging projects as the A303 works around Stonehenge, the A27 Arundel scheme, the Lower Thames crossing, the Port of Liverpool access road, the Silvertown tunnel in London and the Wensum Link road in Norfolk. A government seeking to protect the lives of current and future generations would immediately strike down the policy that supports these projects, and replace it with one that emphasised walking, cycling and public transport.
A third action has been launched by Chris Packham and the law firm Leigh Day, challenging HS2 on similar grounds. Its carbon emissions were not properly taken into account, and its environmental impacts were assessed before the government signed the Paris agreement.
Already, the Heathrow decision is resonating around the world. Now we need to drive its implications home, by suing for survival. If we can oblige governments to resist the demands of corporate lobbyists and put life before profit, humanity might just stand a chance.
